74F245  
Octal Bidirectional Transceiver with 3-STATE Outputs  
Enable input, when HIGH, disables both A and B Ports by  
placing them in a High Z condition.  
General Description  
The 74F245 contains eight non-inverting bidirectional buff-  
ers with 3-STATE outputs and is intended for bus-oriented  
applications. Current sinking capability is 24 mA at the A  
Features  
Non-inverting buffers  
Bidirectional data path  
A outputs sink 24 mA  
B outputs sink 64 mA  
Ports and 64 mA at the B Ports. The Transmit/Receive  
(T/R) input determines the direction of data flow through  
the bidirectional transceiver. Transmit (active HIGH)  
enables data from A Ports to B Ports; Receive (active  
LOW) enables data from B Ports to A Ports. The Output
